Bitcoin is still looking south, having hit four-month lows today, but the bearish momentum may wane due to short-term oversold conditions, the technical charts indicate.

More bears joined the party in the U.S. session Tuesday after the cryptocurrency failed to cross twin resistance at $6,859 (50-hour moving average (MA) and 23.6 percent Fibonacci retracement). As a result, the price fell to $6,370 on Bitfinex today, the lowest level since Feb. 6. At press time, bitcoin was slightly higher at $6,453.

The drop to the four-month low has bolstered the already bearish technical setup and raised the odds of a sell-off to $6,000 (February low).

However, the bears may take a breather over the next day or two, as the relative strength index (RSI) is hovering at the key bullish reversal zone, and bitcoin could hold around support at $6,400 or possibly see a minor corrective rally.

Currently, the RSI is holding below 30.00. Historical data shows BTC stages a "V"-shaped recovery every time the RSI drops to or below 30.00. However, things may pan out differently this time, as long-term technical charts are biased to the bears.

The downside break of the pennant (bearish continuation pattern) indicates scope for a drop below the February low of $6,000.

Further, on the weekly chart, the RSI fell below key support of 53.00 in February, signaling a long-term bullish-to-bearish trend change and is currently hovering below 50.00 (still in bearish territory). Clearly, the bears now have more say in determining the BTC/USD exchange rate.

So, while the cryptocurrency may make a brief rally, courtesy of the oversold conditions, a major recovery will likely remain elusive.
